A nurse is reviewing laboratory results for four clients who are scheduled for surgery. Which of the following laboratory values should the nurse report to the surgeon?

Platelets 95,000/mm

MCT 42%

WBC count 8,000/mm

INR of 1.6

Answer and Explanation

The Correct Answer is A

A platelet count of 95,000/mm is below the normal range of 150,000 to 400,000/mm and indicates thrombocytopenia, which increases the risk of bleeding during surgery. The nurse should report this value to the surgeon and anticipate interventions such as transfusion of platelets or postponement of surgery. The other values are within normal limits and do not require immediate attention.

Correct Answer is D

Explanation

Desmopressin is a synthetic form of antidiuretic hormone (ADH), which regulates water balance in the body. Diabetes insipidus is a condition caused by a deficiency or resistance to ADH, resulting in excessive urination and thirst. Desmopressin helps reduce urine output and prevent dehydration by mimicking the action of ADH on the kidneys. Lithium is a mood stabilizer that can cause nephrogenic diabetes insipidus by interfering with the response of the kidneys to ADH. Regular insulin is used to treat diabetes mellitus, not diabetes insipidus, as it lowers blood glucose levels by facilitating its uptake into cells.

Furosemide is a diuretic that increases urine output and can worsen dehydration in clients with diabetes insipidus.

A. Creatinine 0.8 mL/dL B. Weight gain 1.1 kg (2.4 lb) in 24 hr C. Peripheral pulses 2+ bilaterally D. Urine specific gravity 1.045

Correct Answer is B

Explanation

Weight gain 1.1 kg (2.4 lb) in 24 hours indicates fluid retention and possible volume overload, which can worsen kidney function and cause complications such as hypertension, pulmonary edema, and heart failure. The nurse should report this finding to the provider and monitor the client's vital signs, fluid intake and output, and electrolyte levels.

Creatinine 0.8 mL/dL is within the normal range for adults and does not indicate kidney impairment. Peripheral pulses 2+ bilaterally are normal and do not suggest any vascular problems. Urine specific gravity 1.045 is slightly high but not abnormal for a client with acute kidney failure, as it reflects the reduced ability of the kidneys to dilute urine.
